About the site - Copyright restrictions issues and how to use the site


ALL of the website resources are FREE TO USE ON-LINE as a class resource as long as the pages are NOT COPIED into any electronic/CD/DVD storage system INCLUDING MOODLE, INTRANETS, BLOG SITES or EXTERNAL SCHOOL INTERNET SITES etc. etc.! i.e. anything!

None of my own work is to be used or copied in the production of any webpage for the internet or an intranet.

I retain all copyright of ALL the content of the Hot Potato quizzes.

(Hot Potato is a free software package if your work is made available free online)

ALL site content, unless otherwise indicated is of Dr W. P. Brown 2000-2015 - I'm a 'one man band'!

The only four pages free of copyright restriction are the 3 mini-site maps for

KS3 science, GCSE science-chemistry, Advanced level chemistry

and the GCSE chemistry notes absolute URL link page.

 You may copy and edit these pages to suit your own purpose in linking to specific pages on my site BUT nothing else!

Sadly, I have already had to contact several schools on breach of copyright issues.

I make no apologies for running the two advert streams - now many years retired from science-chemistry teaching, the revenue pays for the web hosting site, domain name, computers, latest textbooks etc. However, I don't endorse the adverts personally AND I never mix the ads with the science-chemistry. The adverts are at the top and bottom of the page with lots of detailed 'unadulterated' notes between!

MAIN Science-CHEMISTRY AREAS and Question Style

click on icons guide used for navigation links * Feel free to email your thoughts on anything about the site

  • INTRODUCTION - how you and your students can help!


    • I write 'old fashioned' textbook style notes and try to write to the highest academic level needed for a particular course.

    • The pages are written in simple old HTML 4.01 ? and I see no reason to write in elaborate style sheets.

    • The more sophisticated code for quizzes is provided by the free to use (if free to use online) 'HOT POTATO' software.

    • I'm aiming to write a completely integrated chemistry website to cover anything encountered before university (initial encounter age usually 11-18). There will be increasing links, backward/forward, and upward/downward, to aid transition from one academic level to another.

    • What do you, or your students, like or dislike about the site?

    • What country/course are your students doing? I'm UK based and its sometimes difficult to relate to other countries national grades or levels, so can you please help?

    • Suggest improvements? Email any possible Q or revision note errors AND any broken link (there are over 3000+ Q's and 4000+ links in the site!). 

    • Encourage the students to be familiar with the icon system and the academic level of the web pages.

    • The Google [SITE SEARCH] box is dedicated to this site, you can enter whatever key words or formulae etc. - even fragments of equations!

My www so far!

I am interested in equating the UK science education levels for 11-18 year olds with academic levels in other countries.  This site should always be free to use on-line, Google Adsense adverts pay for all the internet-broadband and web hosting fees and hopefully a new faster computer in the future and I try to ensure that most adverts in the science-chemistry sections concern educational material. The more advanced level pages are particularly suitable for pre-university chemistry courses in Australia Brazil Canada China India Ireland New Zealand Singapore South Africa USA
